The Science Behind Epoxy Flooring: Composition Explained

Epoxy floors are a popular choice for garages and other residential spaces, but they also provide durability and a polished look in industrial settings. They can withstand heavy machinery, chemical spills, and high foot traffic.

But what exactly makes up an epoxy floor coating? It consists of two main components: resins and hardeners.

Resin

Epoxy resin is an incredibly durable and strong polymer that is chemically bonded to hardener to create a smooth, protective and brightly coloured floor coating, but the installation process is complex . Epoxy flooring is renowned for its long lifespan and can easily withstand the weight of heavy machinery, vehicles or other large objects. It is also completely water-resistant and will not suffer from any damage if contaminated with chemicals or oil spillages.

As a result, epoxy flooring is often used in industrial environments where safety is a priority and it protects concrete floors from damage and corrosion. However, it can be utilised in any high traffic area that needs a durable coloured floor covering.

Typically, epoxy resin is created in a process that involves mixing a base resin with a curing agent and applying it directly to the concrete substrate. This is followed by an application of a metallic flake or aggregate blend to enhance specific properties such as extra impact resistance, slip-resistance or strength.

There are various types of epoxy available, including solvent-based, water-based and UV-cured epoxies. These differ in their ability to penetrate and cure, and the chemical makeup of the resin itself will determine which one is best suited for a particular project.

All epoxy coatings require a suitable concrete substrate that is well-prepped. Ideally, any cracks must be filled and the surface cleaned thoroughly. The underlying surface should be free of grease, oils, solvents or dust to ensure that the epoxy adheres effectively and is able to withstand its intended use.

When correctly installed by an experienced and professional team, epoxy flooring offers many benefits. The smooth, non-porous surface makes it easy to clean and is hygienic in environments that must comply with stringent health and safety guidelines. The reflective sheen of the epoxy resin also improves lighting in large facilities, saving money on additional electrical costs and ensuring that workers can see clearly.

Epoxy is a cost-effective solution for any business looking to upgrade their existing concrete or timber surfaces. The durability and longevity of epoxy flooring means that the initial investment will quickly be repaid over time, especially in terms of reduced maintenance costs.

Hardener

When epoxy resins are combined with hardeners, they chemically react to form a highly durable, rigid thermoset plastic material. Unlike do-it-yourself paints that rely on evaporation to harden and dry, industrial-grade epoxy flooring uses a controlled chemical reaction between carefully calibrated resins and hardeners.

Epoxy floors are extremely durable and long-lasting. They can withstand a wide range of temperatures and chemicals, as well as heavy machinery. They can also be augmented with contrasting vinyl chips and other additives to provide a more decorative look.

The science behind epoxy is intriguing. Despite being liquid or paste-like when applied, epoxy is able to transform into a tough, hardened surface by undergoing a series of cross-linking reactions between hydroxyl groups that are already present in the resin and chemical units in the hardener. Once the hydroxyl and chemical groups are linked together, they form covalent bonds – a type of strong chemical bonding in which electrons are shared between atoms.

These bonds are responsible for the epoxy’s high tensile strength and thermal stability. They are also what give epoxy its resistance to abrasion and impact damage. Another advantage of the epoxy-hardener combination is its low permeability. Its ability to withstand moisture and other contaminants makes it a good choice for high-traffic areas where spilled materials would otherwise cause stains or corrosion.

When mixed and applied properly, epoxy is a safe and durable flooring solution for businesses. It is also hygienic and easy to clean. Unlike carpets, which can trap dirt and debris that could lead to accidents, epoxy floor coatings are non-porous and therefore require no harsh cleaning products.

The application of epoxy floors requires the skill of an experienced flooring contractor. The underlying surface must be prepared correctly and free of cracks, grease, oil and solvents, before the epoxy can be installed. The ratio of the resin and hardener must be exact to achieve a successful outcome. The chemistry that takes place is temperature-dependent, so it must be performed on the job site within the appropriate time window.

In addition, the mixing and curing of the epoxy itself needs to be carried out by a qualified contractor. Failure to follow the correct procedures could result in a sub-par finished product that is less durable and resistant to wear and tear.

Polymer Chains

If you’re considering installing epoxy floors in your commercial or industrial space, it is good to know that the chemical makeup of these floors makes them incredibly strong. The durable surface is capable of withstanding heavy impacts, such as from vehicles and machinery, without damage. In addition, it is highly resistant to chemicals and stains. This is why it’s often used in warehouses and manufacturing facilities.

Epoxy floor coatings are available in a wide range of colours and textures. These can be used to create designated zones in a large facility, for example, to indicate areas for foot and machine traffic. The hard-wearing, non-porous surface also provides a good level of slip resistance and prevents static charge buildup on the floor, which can damage sensitive equipment. There are even antistatic systems that comply with ESD standards and transfer the static charge to defined earthing points.

When applied to a properly prepared surface, epoxy flooring is water-resistant, which means it will not be affected by floods or spillages of oil or other chemicals. It is also easy to clean, which makes it ideal for commercial spaces that may experience occasional accidents or incidents that require immediate attention, such as fires. In fact, this is why epoxy is so popular in fire stations – the fire-resistant floors can be hosed down with water to quickly and easily remove any toxins that have been spilt.

For those who want a more organic solution, 100% solids epoxy products do not use a solvent and instead consist of only resin and hardener. This does mean that the pot life is much shorter, but it can be mixed and applied straight away without the need for a solvent.

The shiny finish of epoxy floorings not only looks great in garages and other residential spaces but is also a welcome feature in larger facilities, where it helps to improve lighting by reflecting light around the room. In addition, the smooth surface is very easy to clean, which helps keep it hygienic and free from dirt, bacteria, dust and other debris.

Covalent Bonds

Epoxy is an incredibly popular flooring option for commercial spaces, industrial buildings and garages. Its impressive durability and resistance to impact damage and chemical spills are due in part to the unique chemistry of its composition. Understanding what makes epoxy flooring so strong and durable can help you make the best choice for your space.

Epoxies are composed of polymer resin and hardener that create a dense, durable coating that is highly resistant to impact and chemical damage. During the curing process, epoxy resin molecules bond together to form long polymer chains. This structure gives epoxy its high tensile strength and resilience, and also contributes to its ability to withstand temperature changes.

In addition, epoxy coatings are non-porous, meaning they don’t absorb water or other liquids that can stain the underlying concrete. This is a major advantage for facilities that need to keep floors clean and dry. Epoxy floors are easy to maintain and can be cleaned with simple household cleaners, saving time and money on cleaning supplies.

Once the base layer of an epoxy floor is applied, decorative add-ons can be added for aesthetic appeal and to enhance safety or functionality. For example, anti-slip additives can be used to provide a textured surface that increases slip resistance, while colored flakes can give the floor an appealing color.

Before any application of epoxy, the concrete floor needs to be thoroughly cleaned and prepped. This includes removing any existing floor coverings and repairing any cracks or damaged areas in the concrete. Once the surface is clean and free of debris, a primer layer is applied to ensure that the epoxy adheres properly. Once the primer is cured, the base coat of epoxy is then applied.

The top coat of epoxy serves as the final layer of protection, adding to the overall durability and chemical resistance of the floor. Once cured, the top coat can be textured or colored to achieve a specific look.

In addition to its physical properties, epoxy is a very energy-efficient flooring solution. Its radiant heat-retention capabilities mean that you don’t need to use as much power to keep your facility warm, and it helps minimize the need for extra lighting, again reducing energy costs. In addition, its longevity means that you don’t have to replace your flooring as often as other types of floors, further cutting your costs.
